Tracing of gasses liked to biologically related activities in mars would soon be triggered with the launching of the new EXOMARS ORBITER which is expected to be near mars within the next few days. The primary reason for this search could be explore the possibilities of life sustaining elements on this planet. NASA reportedly stated that it could find traces of methane around the planet, further fuelling the speculations of life. No solid evidence has been produced so far by the scientists and space researchers in this regard so far. Many missions have already been launched for detecting the presence of water within the inner layers of Mars’ land surface. They could lead to the probability of establishing “human colonies” in mars in the future years!
Landing on Mars
The first known landing on Mars started with the Viking expedition in 1976 July. Viking 1 has successfully sent vital data and information from the surface of Mars over many decades. It worked for more than 2300 days, travelling on the varying conditions and analyzing all types of soil, rock and other samples.
Viking was loaded with several analytical and research equipment which could perform studies into the existence of life. Most of the studies have been centred on the chemical reactions which take place in the Mars soil due to its interaction with life. There are a lot of differences between the organic chemical reactions which results from lively species and the inorganic reactions that happen due to interaction of chemicals. The scientists are still divided over the outcome of studies related to chemical reactions on the Mars soil.
Microbial Life on Mars
After failing to find life on the surface of Mars, the scientists are now turning their attention to the probable existence of microbial life within the inner layers of Mars’ surface. There have been widespread speculations that this experiment could lead to positive results. The baffling feature of this research is the “firm belief” expressed by NASA about the existence of life on Mars.
If you start probing deep into the research, you may be surprised to learn about the reasons for NASA’s insistence. There have been substantial proofs of radioactive carbon moving vertically upwards in Mars. The same phenomena were observed when similar experiments were conducted with microbial life on earth.
Minerals on Mars
Apart from possible life, there is scope of getting plentiful of useful minerals in Mars which could be sufficient to fulfil the energy requirements of earth for many centuries into the future. However the methods and means of transporting these minerals back to earth from this planet seems to be an impossible task. That could be another reason for NASA to look for life here, so that humans can go and settle in Mars which is said to be simpler and effective in nature. Once any positive results are obtained from the experiments to search for life, the next steps to shift human population onto Mars won’t be far away, say the scientists from NASA.…
